Abstract
In this slide apparatus, screw shaft supports adapted to support a screw shaft constituting a feed screw mechanism by which a slider is slidingly moved on a track rail are placed on and fixed to an upper surface of the track rail, and one end portion of the screw shaft is supported on a bearing fixed to a bearing support metal member of a thin steel sheet provided on one screw shaft support, whereby the assembling efficiency of the apparatus is improved. The slider is moved forward and backward in a recess of the track rail by a rotational driving force of the screw shaft engaged with a nut provided on the slider. The screw shaft supports supporting end portions of the screw shaft so that the screw shaft can be rotated freely are fixed in a bridged state to a pair of raceways of the track rail. When the lead of the feed screw mechanism is changed or when maintenance work is carried out in this slide apparatus, the screw shaft supports are removed simply from the track rail, whereby the screw shaft and nut can be removed simply from the slider. This enables the working efficiency to be improved.
